The composition of this invention is an inorganic oxide particulate comprising at least 10% by weight organic material in which the particulate has an auto- ignition temperature which is at least 20 ~C higher than the auto-ignition temperature of the particulate and organic material which does not contain antioxidant and/or inhibitor. Accordingly, a method has been developed in which one is able to elevate the auto-ignition temperature of such organic containing particulates. In a preferred embodiment the method comprises including antioxidant or inhibitor in the organic material prior to combining it with the organic oxide.
L'invention concerne une composition qui constitue une matière particulaire d'oxyde inorganique renfermant au moins 10 % en poids d'une matière organique dans laquelle la matière particulaire a une température d'autocombustion supérieure d'au moins 20 ·C à la température d'autocombustion de la matière particulaire et de la matière organique qui ne contient pas d'antioxydant et/ou d'inhibiteur. Selon cette invention, on a développé un procédé, selon lequel on peut élever la température d'autocombustion de telles matières particulaires organiques. Dans un mode de réalisation préféré, le procédé consiste à incorporer un antioxydant ou un inhibiteur dans la matière organique avant de la mélanger à de l'oxyde organique.
